Summary: This adds very little (no?) new features and mostly just refactors code to live in a singular place. Instead of users having to worry about DebugComponent as well as the DebugInfo object and attaching it correctly to a tree now user's of the DebugComponent API only need to worry about a single class, greatly simplifying its usage.
